Abstract
A bed-like stretcher for supporting a patient includes a bed surface frame pivotally connected to a base. A gas spring fixes the frame in position relative to the base. A hand-operated actuator mounted to the frame is moveable in first and second opposite directions, and is biased into a normal position. A rod connects the actuator to a release rod for the gas spring, whereby movement of the actuator in either direction releases the spring to permit pivotal movement of the frame. A stop bar is secured to the frame to be adjacent an upward-facing stop surface on the base when the frame is horizontal. The bar is biased into contact with the stop surface when the frame is horizontal to prevent downward pivotal movement of the foot end. A cable connects the stop bar to the actuator, whereby movement of the actuator in one direction causes the cable to slacken and movement of the actuator in an opposite direction causes the actuator to pull the cable to withdraw the bar from contact with the stop surface.
